Patent DE-3303326-A1 (DE)
Title: Pressure-relief flap
Inventor: STAATZ GUENTER DIPL ING
IPC: E06B5/12
Filed: 1983-01-28
Abstract: A pressure-relief flap is described, which in the closed state airtightly seals a space which is subject to overpressure or underpressure and opens automatically in the event of an increased pressure shock occurring on one side. The flap is mounted in a door and sealed on both sides by films which bridge the circumferential gap between door and flap, the films being pressed against the door by flexible permanent magnet bands so that, during opening of the flap as a result of a suddenly occurring pressure shock, the films can slide out under the permanent magnet bands. A catch closure, which is adjustable so that the pressure at which the flap opens can be regulated, serves as closure for the flap.

Title: Device for contactless measurement of the distance of a metallic test specimen from a sensor coil
Inventor: DOBLER KLAUS DR
IPC: G01B7/02
Filed: 1983-02-18
Abstract: A device for contactless measurement of the distance of a metallic test speciment (M) from a sensor coil (10) is proposed which has a generator (20) for generating at the sensor coil (10) an ac voltage serving as carrier signal, the one output terminal of which generator is connected via a series resistor (RV) to the sensor coil (10), the coil-side end of the series resistor (RV) being connected via a rectifier (D) to a storage capacitor (C1) with a parallel-connected discharge resistor (R2), and the other end of the discharge resistor (R2) being connected to the end of the sensor coil (10) which is directly connected to the generator (20) and, furthermore, the distance-dependent output voltage (Ua) being tapped at the discharge resistor (R2). In this case, the measuring frequency is provided by a carrier frequency which is smaller than the resonance frequency of that resonant circuit which is formed by the sensor coil (10) and a series capacitor (CR) which is arranged in the connecting line between the series resistor (RV) and the sensor coil (10). The series capacitor (CR) simultaneously serves in this arrangement to invert the measurement signal (Ug<-) occurring at the sensor coil (10). The current flux (i) thereby rising with increasing distance (a) between the sensor coil (10) and test specimen (M<-) is in this case for the purpose of linearisation of the measurement value display (Ua) by corresponding ...

Patent DE-3318841-A1 (DE)
Title: Process and equipment for producing nodular graphite cast iron
Inventor: MARKE KARL-HELLMUTH DIPL ING D
IPC: C21C1/10
Filed: 1983-05-24
Abstract: The conventional procedures in the production of nodular graphite cast iron by means of pure magnesium in iron foundries are affected by substantial disadvantages. These include low productivity per unit time, high transport costs, intensive personnel use, inaccuracy of the magnesium analysis in the cast iron and high magnesium losses from the cast iron melt as a function of time. To solve the problems, a process and equipment have been found in which the equipment forms a treatment space in a treatment vessel bottom, the treatment vessel being filled with molten cast iron and the latter penetrating into the treatment space filled with pure magnesium. A reaction of the magnesium to form a magnesium alloy in the molten cast iron then takes place. A treatment vessel has advantages if it is designed as vacuum treatment vessel, because in this case, in conjunction with a cast iron receiver, partial automation of the step of filling of the treatment vessel is possible via a level indicator with control. If the finished molten cast iron must be held in the vacuum treatment vessel for a prolonged period, magnesium losses are avoided by the use of blanketing gases.

Patent DE-3330082-A1 (DE)
Title: Kit for an inclined hoist
Inventor: MORYS KLAUS
IPC: B66B9/16
Filed: 1983-08-18
Abstract: Roofers have inclined hoists with ladders which can be retracted and extended telescopically and thus linearly. A slide with a motor can travel back and forth on the pushed-apart ladders. When the ladders are pushed apart, the inclined hoist is placed with these ladders against a roof edge. Building material can then be conveyed by the slide onto the roof. In many cases, the top ladder should be folded and then placed onto the roof surface parallel to the same. The kit according to the invention is used for this purpose. It essentially consists of two sections, connected to one another in an articulated manner, and a mounted head piece. The two sections are pushed into the top ladder of the existing inclined hoist. They then form a folding top ladder in the inclined hoist. When required, the roofer pulls this top ladder out of the original top ladder of his inclined hoist. He can fold the top section and place it in parallel onto the roof surface. The advantage of the kit according to the invention is that the roofer, by using the kit, can inexpensively convert his existing inclined hoist into such an inclined hoist with a folding top ladder.

Patent DE-3335407-A1 (DE)
Title: Safety device for electromechanical opening and closing mechanisms
Inventor: KAWAI TANEICHI
IPC: H02H7/085
Filed: 1983-09-29
Abstract: A safety device is specified for an electromagnetic opening and closing mechanism for example such a mechanism for a motor vehicle sliding roof, which safety device interrupts a circuit for driving the mechanism if, in an abnormal case (such as a foreign body being trapped in the mechanism, for example), the circuit load exceeds a specific nominal value. The nominal value is in this case one of two nominal values. A first nominal value changes as a function of the load. A second nominal value is determined by the position of the moving part of the mechanism. The safety device comes into action when a load exceeds one of the two nominal values. The first nominal value comes into action in the event of a load change, and especially in the event of a load reduction, in such a manner that a sensitivity reduction of the safety device is prevented, while the second nominal value comes into action in the event of a load rise, and especially in the event of a slow load rise, in that the mechanism is prevented from being overloaded. In this way, the safety device prevents damage to the mechanism and to the foreign body which is trapped in the mechanism, while the device maintains high sensitivity.

Title: Device for discharging solids from positive displacement pumps having a frontally axially arranged inlet and outlet duct
Inventor: HOELZ HERBERT DIPL ING
IPC: F04B53/10
Filed: 1984-02-09
Abstract: For the purpose of discharging solids from positive displacement pumps having a frontally axially arranged inlet and outlet duct, a vane is arranged upstream of the point separating the discharge and the suction duct, which vane deflects the flow into the outlet cross-section of the discharge duct. This outlet cross-section extends over the vane and the point of separation, and in a radial direction extends beyond the outer radius of the displacement vanes. The invention prevents foreign bodies contained in the liquid to be delivered from forcing themselves into the controlled gap seal between outlet and inlet duct and from causing wear of this controlled gap seal.

Patent DE-3419201-A1 (DE)
Title: Gripper device
Inventor: POLLANDT WERNER
IPC: B41F21/10
Filed: 1984-05-23
Abstract: The invention relates to a gripper device on cylinders of sheet-processing machines, in particular sheet-fed rotary printing machines. In the gripper systems generally known on such machines, strong sound pulses occur when the grippers are opened due to the gripper fingers striking against the adjusting screws arranged for setting the lifting time and consequently structure-borne noise is fed via the gripper shaft up to the control cams. According to the invention, this sound level is considerably reduced in that the striking surfaces of the gripper finger and of the adjusting screw are coated with a material which has greater damping than steel or cast steel and has soundproofing properties, and in that a sliding clip consisting of material with the same damping properties is assigned to the gripper finger and to the clamping piece which holds the gripper device on the gripper shaft.

Title: Steering-column switch for motor vehicles
Inventor: ERDELITSCH HERBERT
IPC: H01H1/36
Filed: 1984-11-08
Abstract: A steering-column switch for motor vehicles has a switching element which is supported in a housing such that it can pivot about an axis and can be moved via a switching lever between a null position and an operating position. The switching element carries a contact link which is supported in a sprung manner on the switching element, at right angles to the pivoting axis, and by means of which two stationary contacts, which are parallel to the pivoting axis, can be acted on. In order to achieve good contact making with little stress on the switching element and on the contact link, the two stationary contacts are arranged such that the spring force which acts on the contact link when changing over from the null position into the operating position is increased. Furthermore, a design is preferred in the case of which the two stationary contacts are essentially flat and are arranged at such an angle with respect to one another that the contact link is adjustable without being tilted in the pivoting plane.
